DRILL.

SPECIFICATION'forming part of Letters Patent No. 627,830, dated June 27, 1899.-

Application filed January 16, 1899. Serial No. 702,384. (No model.)

To all whom itmwy concern.-

Be it known thatI, JOHN RoDENBERoEan.

citizen of the United States of America, and

a resident of Friendship, in the county of Cherokee and State ofKansas, have invented facilitate the handlingand the movements of the drill, so as to secure a steady'forward movement of the seeding-axle, and thus relieving the team of all burdensome weight upon the neck, and, secondly, to provide r 5 means whereby all the grain can be planted at the same depth on the same line orlevel at any desired depth.

My invention consists in novel features of construction hereinafter described and claimed, .whereby I carry out the object of my for clearness of illustration, though there may invention. i

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in

2 5 which-.

Figure I is' a perspective view of my im-' proved grain-drill provided with one of my seeding devices. Fig. II is a side elevation of the seeding device. Fig. IIIis a'central 3o longitudinal section of the seeding device,

the colter being shown part in elevation and part in section. tion of the seeding device.

1 is the main frame, which is mountedon an axle 2, which in turn is supported on a pair of ground-wheels 3. Extending from the main frame is a draft-frame constructed with an outer part 4, converging toward the front end of the machine, with a middle part 4 branching outward and downward toward the rear end of themachine, and with an inner part consisting of two longitudinal bars 4 secured by fastenings 5 to the side bars 5' of the main frame. The outer part of the draft-frame is supported on a pilot or truck comprising an arched-axle 6, whose spindles 6 are journaled in a pair of truck or pilot wheels7. v V

8 is a tongue having upper and lower tongueplates 9, which'are secured by bolts 10at the inner end, where' it is supported on the truck or pilot. The arched axle, the tongue-plates,

Fig. IVis a rear end elevaand the outer partfof the draft-frame are coupled together by a center or king bolt 11. The tongue is also braced and supported from the spindles o of the arched axle by means of stay-rods 12, which are loopedat their lower endsaround the spindles and at their I upper ends are also looped around a transverse bolt 18, extending through or across the tongue. The longitudinal bars 4 are con- 'nected together in front of the main frame by means of a brace-bar 14. 1

15 is a rock-shaft having a hand-lever 16 and fulcrumed in clips 17, secured to the longitudinal bars 4? between the main frame and the brace-bar 14. To this rock-shaft are secured a pair of radial eye-plates 18 for supporting the pin 19, to which the front end of the runner or cutter of my seedingdevice is coupled.

I merely show one of my seeding devices be two or more arranged in gang form, as usual. Each of my seeding devices is constructed with a runner or cutter formed with "a body 20 of trough or shape in cross-section, so as to form a similar-shaped seed-furrow in the'surface of the ground over which it is trailed. The runner is also formed with r a breast part 20 for opening the seed-furrow,

with anupwardly-curved neck 20, and'with a head 20,having hooks 2O engaging the pin 19 of the eye-plates 18, whereby the run- .ner is loosely coupled to the rock-shaft 15, so

as to ride on the surface ofv the ground. The body of the runner is providedwith a longitudinal opening 20 through which a rolling on rotary colter 21 and adjustable seed-shoe 22 project and. operate. The colter has a shaft 21, whereby it is journaled in short forward standards 23, soon red within the body 20 just inrear of the breast part 20, so that the colter projects through the longitudinal opening 20 and below the body. Located in rear of the colter within the body aretwo pairs of rear standards 24, each having a ver- 'tical series of holes 24 and secured by fastenings 25 to opposite sides of the longitudinal opening of 'the body. Between .and to these standards 24 my seed-shoe is adj u'stably secured. This seed-shoe is composed of a pair of plates 26, bulged at their middle parts, secured together at their ends by fastenings to register with the vertical series of holes 24 in the rear standards 24:, so as to adapt'the 27, and provided with holes 26 at their upper edges, near their ends, which are adapted seed-shoe to be adjusted at both ends between the rear standards to requisite height and to be secured by transverse bolts or pins 28, whereby the seed-shoe is supported. Between the rear parts of the curved plates is a spacing-piece 22*, over which is an opening 22", through which the seed issues at the heel of the seed-shoe.

29 is a seed-tube pivoted at its lower end by a cross-rod 30 to the seed-shoe, so as to deliver the seed to the latter'for distribution. The front end 26 of the seed-shoe is sharpened, so as to follow in the cut made by therotating colter.

31 is a seedbox connected by a rubber seedfluke 32 with the seed-tube 29. For the purpose of holding down the rear end of the runner or cutter to its work or for elevating it in going to or from .the field I provide the following means: 33 is a spring connected at its lower end to therear end of the runner and at its upper end to the short arm 34 of a hand-lever 34, mounted on a rod 35, supported on the rear end of the main frame.

The truck or pilot located under the front end of the draft-frame permits each wheel to play underneath the front end of the draftframe, thus enabling the team to swing aquarter-circle perfectly independent, when a forward movement of the team turns the machine.

By the combination of the V-shaped runner or cutter colter and the peculiar construction and mounting of the seed'shoe I am enabled to form a furrow in the surface of the ground in advance of the colter, which is set deeper than the seed-shoe, so as to clear the way for the seed-shoe by severing all weeds and trash in advance thereof and preventing choking and clogging of the seed-shoe, which is sharpened on its forward end and adjustable in depth. The seed issues from the seed-shoe over the spacing-piece at the bottom through the opening at the rear end of the seed-shoe.

The V-shaped runner or cutter acts or, serves as a perfect gagein passing over unevensurfaces and high loose earth, and the seed is thus deposited or trailed into the furrow at any desired depth below the bottom of the runner.

Having thus described my invention, the following is what I claim as' new therein and desire-to secure by Letters Patent:
